piperine

Introduction The clandestine manufacture of MDMA is most commonly performed via a reductive amination of 3,4-methylenedioxyphenyl-2-propanone (MDP2P). Most synthetic routes leading to this precursor begin with materials that already contain a pre-installed methylenedioxyphenyl moiety such as...

let me preface this by saying yes, i know @WillD made a lovely thread, but these links go "further back" and start the process earlier. his synth starts with MDP2P which is in the second to last/last links on this list. i just wanted to put that out there so this doesn't get considered redundant...

Stage 1. Extraction of Piperine Starting reagents and materials: 400 ml of 88% ethanol 300 g of ground black pepper Potassium hydroxide (KOH) 180 mm diameter filter papers Soxhlet extractor (500 ml) Measuring cups Funnel Heater Pour 300 ml of 88% ethanol into a 500 ml flask. Place 60 g of...

I found this pretty awesome paper showing how to make MDMA from some pretty useful methods. My favorite part is Piperonal directly from piperine using ozonalysis: But there are like 3 other methods outlined. All very approachable from an amateur setting. Sci-Hub link and PDF attached. Enjoy.

Hi, This is my first big project in organic chemistry. So your help is welcome. My theory is isolate a piperine from black pepper and convert to a piperic acid. And reaction with potassium permanganate cause a oxidative cleavage and makes piperonal and piperonylic acid (Is possible this acid...
